what should I do?

A little bit ago I was feeling cramping and whipped and have very light brown/pink spotting. I actually am still having it. But it's just spotting and very very light. Af is due the 6th. Not sure if that's normal or implantation. I haven't been able to get pregnant in over a year so idk if it'd really be that good of a chance. But we did have sex the day before or the day I ovulated. So I'm not to sure. I haven't felt a whole lot different that I could think of. Anyways my issue is my SO is drinking with his buddies and I'll be home soon that they'll still be up so I kind of wanted a drink as well, but idk if I should or not because of what's going on. Thoughts/advice?
